Substantial doubt about the company's ability to continue as a going concern.
“Management has determined that the Company does not have sufficient liquidity to meet its current obligations, which is considered to be one year from the date of the issuance of the accompanying unaudited financial statements. In addition, Management has determined that if the Company is unable to complete a Business Combination within the Combination Period, then the Board would proceed to commence a voluntary liquidation and thereby a formal dissolution of the Company. These conditions raise substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Aug 13, 2026

How the mix is measured
Shares are 13F common shares restated to today's split basis; options and principal amounts are left out. The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none was. Actively managed books are those measured systematic-like, concentrated or diversified active.
Conviction and Crowding
26 13F filers, quarter ended Jun 30, 2026Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts filers with high turnover or that advise private funds on Form ADV.
Managers in the top fifth by current three-year FundScore alpha were net buyers of $0 (0 buying, 0 selling).
